+# Deploy Current Branch Action
+
+This GitHub composite action builds a Docker image from the current branch commit and deploys it to a KubeVela cluster for development testing.
+
+## What it does
+
+- Generates a unique image tag from the latest commit hash
+- Builds and loads the Docker image into a KinD cluster
+- Applies KubeVela CRDs for upgrade safety
+- Upgrades the KubeVela Helm release to use the local development image
+- Verifies deployment status and the running image version
+
+## Usage
+
+```yaml
+- name: Deploy Current Branch
+  uses: ./path/to/this/action
+```
+
+## Requirements
+
+- Docker, Helm, kubectl, and KinD must be available in your runner environment
+- Kubernetes cluster access
+- `charts/vela-core/crds` directory with CRDs
+- Valid Helm chart at `charts/vela-core`
+
+## Steps performed
+
+1. **Generate commit hash for image tag**
+2. **Build & load Docker image into KinD**
+3. **Pre-apply chart CRDs**
+4. **Upgrade KubeVela using local image**
+5. **Verify deployment and image version**

+# Setup Kind Cluster Action
+
+A GitHub Action that sets up a Kubernetes testing environment using Kind (Kubernetes in Docker) for E2E testing.
+
+## Inputs
+
+| Input | Description | Required | Default |
+|-------|-------------|----------|---------|
+| `k8s-version` | Kubernetes version for the kind cluster | No | `v1.31.9` |
+
+## Quick Start
+
+```yaml
+name: E2E Tests
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      
+      - uses: actions/setup-go@v5
+        with:
+          go-version: '1.21'
+      
+      - name: Setup Kind Cluster
+        uses: ./.github/actions/setup-kind-cluster
+        with:
+          k8s-version: 'v1.31.9'
+      
+      - name: Run tests
+        run: |
+          kubectl cluster-info
+          make test-e2e
+```
+
+## What it does
+
+1. **Installs Kind CLI** - Downloads Kind v0.29.0 using Go
+2. **Cleans up** - Removes any existing Kind clusters
+3. **Creates cluster** - Spins up Kubernetes v1.31.9 cluster
+4. **Sets up environment** - Configures KUBECONFIG for kubectl access
+5. **Loads images** - Builds and loads Docker images using `make image-load`
+
+## File Structure
+
+Save as `.github/actions/setup-kind-cluster/action.yaml`:
